Mallard is an interactive learning environment on the World Wide Web, suitable for virtually any subject. Mallard provides a secure environment within which one can organize online course material and test students via interactive quizzes with instantaneous problem correction and grading. Questions can be either randomly generated (if appropriate) or randomly selected. Administrative utilities include viewing up-to-the-minute tables of student progress, choosing grading policies, and posting announcements and due dates. Since quizzes are submitted and graded on-line; the instructor does not have to collect, correct, or even record grades. For further information, see our Website at http://www.cen.uiuc.edu/Mallard.

The Sloan Foundation has established the Sloan Center for Asynchronous Learning Environments (SCALE) on the University of Illinois at Urbana-Champaign campus. The goals of the center are (1) to assist faculty in the restructuring, development, and delivery of asynchronous learning network (ALN)-based courses on the UIUC campus, (2) to promote, disseminate, and diffuse the ALN concept widely on the UIUC campus and on the other campuses, and (3) to investigate the impact of ALN on student learning and faculty productivity.

A freshman Discovery course on medical imaging is being enhanced by greater use of asynchronous learning technologies. Conferencing software is used to extend faculty office hours and to promote interaction of students on projects. Automated grading of quiz materials is used for reenforcement learning. Course notes are delivered via the World Wide Web, with links to explanatory material and backward links from the quiz problems. Examples of medical imaging in practice are linked to national databases relevant to the disease or medical problem.

Asynchronous learning technologies are being used to enhance the activities in a senior bioengineering course. Extensive use is made of electronic means for distribution of course materials and information about students, for execution, writeup and submission of student computer exercises, and for on-line grading of their work. In addition, students use conferencing software to submit homework and term papers and to discuss problems encountered in the course. In the second phase of the project, design problems will be introduced requiring collaboration enhanced by these learning technologies.

We are developing bioengineering courses that meet university general education requirements for nonscience/engineering majors and for training of high school and elementary teachers. In particular, the course Introduction to Medical Imaging is used as a tool to introduce science, math, and engineering concepts.

The ECE Department plans to make the ECE World Wide Web home page the gateway to ``one-stop'' shopping for students interested in ECE activities. In addition to finding descriptive information regarding the faculty, courses, advising, administrative functions, and research activities, any student should be able to access information for any ECE course, including meeting times and office hours, homework assignments, solutions, and notes, and bulletin boards. Support will be made available for advanced graphics, computer simulations, on-line quizzes, and gradebooks.
